Chapter 195: I Want to Save Huaxia Chip

After quitting, Xiao Jun thought about what he would do next.

Thanks to Galaxy Steward's help in developing the virtual game engine, Xiao Jun's busy days finally came to an end. After all, he used to be busy not only with the company, but also with going to class, and developing a virtual game engine.

Now that he has developed this artificial intelligence program for the steward of the galaxy, he is like having a clone.

"As the saying goes, an inch of time is worth an inch of gold, and an inch of gold cannot buy an inch of time. You should cherish your youth." Xiao Jun said with emotion. In short, he doesn't intend to let himself be idle, and now is not the time to sit back and enjoy the benefits!

"My super battery has already taken off, and my Galaxy Technology company has a huge sum of money. It seems that it's time for me to prepare in advance for my future mobile phone company!"

That's right, Xiao Jun intends to develop a mobile phone chip for fun while he has time now?

What is the most important thing about a mobile phone? That's right, that's the mobile phone chip.

Now China needs to import more than 200 billion US dollars of various chips from the West every year, and the total amount of chips imported each year is more than the crude oil imported.

This also shows the importance of a mobile phone chip!

Everyone knows that it is not easy to develop a mobile phone chip with superior performance. You don't know how much manpower, material and financial resources you need to invest. At the same time, the chip you research may still be unable to catch up with others. Because the chip technology is updated too fast, it is updated every year!

If one generation of technology is behind, it is one year or even longer behind!

How many generations should you be behind? You might just eat dust forever!

"It seems that it's time for me to save the Huaxia chip market!" Xiao Jun felt a sense of striving for strength. Since letting others earn the chip money, it is better to let him earn it! Well, the fat and water don't flow into outsiders' fields.

"First of all, the mobile phone chip I developed must be easy to process and durable, and the most important thing is to have superior performance and beat everything!"

Take the first one as an example. If you produce a mobile phone chip with superior performance, but because it is difficult to produce and process, then the final production capacity is low, and you can't even satisfy your own company's mobile phone. How can you sell it to others?

Therefore, easy processing is very important!

Needless to say, it is durable, and the quality must pass the test. As for the chip with superior performance, why should it use a chip with inferior performance?

"Since you want to develop your own mobile phone chip (CPU), you can't imitate other people's methods, and you can't rely on other people's technology. Then everything needs to be innovative and develop something that belongs to you!" Xiao Jun secretly said in his heart. This is very important. If you can't develop an independent chip, what's the use?

Take the currently well-known Kirin 970 chip in China as an example. It is advertised as a self-developed mobile phone chip.

Of course, this can only deceive the people who eat melons!

What are the five major components of a mobile phone chip?

1: Framework

3: Signal processing

4: Communication baseband

5: AI function

First of all, what is the structure? To put it simply, the architecture instruction set! To put it more complicated, set instructions are conceptually similar to CPU processing various calculations. CPU processing calculations also converge small steps into large steps, and the results can be obtained after completing the large steps. The instruction set is the subdivision of the steps that the CPU handles various calculations, but it fixes the various steps as a combination.

If the mobile phone chip is a city, there are several industrial areas and residential buildings (l1l2l3 cache). What the whole city looks like is the structure of the mobile phone chip, how the industrial areas are connected is the multi-core architecture of the CPU, what the industrial area looks like is the structure of the CPU core.

The architecture is the most important core of a mobile phone chip, but the Kirin 970 architecture is not independently developed, but uses the public version of the ARM architecture.

Second, GPU, which is called a graphics processor, display core, visual processor, and display chip, is a microprocessor that specializes in image computing on personal computers, workstations, game consoles, and some mobile devices (such as tablets, smartphones, etc.). The better your GPU, the better your phone's chip performance will be.

The GPU of the Kirin 970 is not independently developed, but uses the Mali series GPU.

Third, for signal processing, the Kirin 970 uses Cadence's DSP, not self-developed!

Fourth, the communication baseband, Kirin 970 is the self-developed Balong750, which is the world's top level in technology.

Fifth, Al, in terms of new functions such as AI, Kirin chips are also leading. The Kirin 970 uses an independent Cambrian NPU chip—that is, an artificial intelligence chip.

But in the end, among the five cores of a mobile phone chip, you use other people's three of them, and you don't independently develop them. Only two of them independently develop your own things.

Strictly speaking, this Kirin 970 mobile phone chip is just a mobile phone chip made up of buying other people's parts and adding some of our own parts, not a mobile phone chip that is completely independently developed!

So Xiao Jun will definitely not do such a thing, he must develop the above five cores by himself!

"Then let's start designing from the structure now." Xiao Jun thought in his heart.

Because he had learned a lot from Halliday before. These include the hardware of the virtual game, the design of the virtual helmet, the design of the host of the virtual game, and other equipment.

As far as the virtual game console alone is concerned, it also has chips in it! Also called processor.

The processors of Halliday's era were certainly ahead of the current Earth.

So Xiao Jun is currently planning to refer to this virtual game console processor, and then combine the current situation to develop a new chip!

"Architecture, since the architecture is so important to a chip, it must be awesome."

"The architecture I designed must be complex and have superior performance!" Because Xiao Jun knows that a complex architecture, that is, a complex instruction set, will be more personalized, so it is more difficult to design, because each instruction needs to complete more complicated actions, but the advantage is high efficiency and fast time. Although the simplified architecture (instruction set) is well designed, each action is divided into more steps, which will lead to lower efficiency and slower execution, and if you artificially increase the clock frequency, the energy consumption will increase.

"So the algorithm in the instruction set must be fast and fast!" Xiao Jun was proficient in programming before, and he had read a lot of books on this topic, and learned a lot of knowledge from Halliday.

He is still very clear about these things!
